v 4 Claims. (01. 20-5) v 1 This invention relates to pre-fabricated shinline with adjacent strips which are not bent gle corner units particularly adapted to be used around the said corners. Starting at thebo'ttom with building covering units of the type generally of a wall at a corner when successive shingles designated as strip shingles. h are placed around the corner over each other in 5 Strip shinglesare ordinarilymanufactured by vertical overlapped relationship, the sloping of 5 coating a base of waterproof roofing felt or simithe said shingles at the corner downwardly and lar materialwith asphalt or the like, then applyoutwardly increases as successive courses of coring'a surface coating of grits, mica, sand or other ner shingles are -placedin vertical overlapping h mineral substance over the asphalt coating'and relationship to the shingles therebelow.

The foregoing is very shingles. d fficult to accomplish in walls covered with strip A'further object of my invention is to provide shingles because, inasmuch as strip shingles are a pre-fabricated shingle comer unit for use with 45 generally tapered downwardly outward with restrip shingles rigidly reinforced to withstand hanspect to a well covered thereby and inasmuch as dling and abuse during shipping and erection. courses of strip shingles vertically overlap each Other objects of the invention will become apother, the said strip shingles will lie in planes parent by reference to the following detailed at downwardly outward angles with respect to description taken in connectionwith the accom 50 a wall covered thereby.

Fig. 5 is a greatly enlarged vertical sectional view taken on the line 5-5 of Fig. 1.

Fig. 6 is a vertical sectional view taken on the line 6-6 of Fig. 3.

Referring now to the drawing wherein like numerals refer to like and corresponding parts throughout the several views, Figs. 1 and 4 show typical pre-fabricated shingle corner construction embodying the invention composed of a one course high pre-fabricated shingle unit A with a three course high pre-fabricated shingle unit B erected in vertical overlapped relationship thereover. The usual overlapped strip shingle wall covering is indicated in Fig. 1 in laterally juxtaposed position to the pre-fabricated shingle corner 'units A and B shown therein. The one course high pre-fabricated shingle corner unit A disclosed, in Figs. 3 and 6 is composed of a brick simulating type strip shingle it having the upper portion ll thereof preferably dark colored and the lower portion i 2 thereof surface coated with a contrasting color of granules or grits of such a nature as to simulate brick. The said strip shingle iii of the comer unit A is bent at the desired angle, for example 90 degrees, and is backed up at the said bend with a similarly bent reinforcing plate l3 preferably of .metal or like substantially rigid reinforcement material which will maintain the shingle corner unit A at the angle to which the said strip shingle I0 is bent.

For convenience, the upper dark portion of the brick simulating type shingles is shown stippled throughout, the drawing and the lower surface coatedportion of the said brick simulating type shingles is shown shaded with vertical shade lines throughout the drawing.

Before bending the said strip shingle II of the shingle corner unit A and backing the same up with the reinforcing plate l3, approximately onehalf of the dark-colored upper portion ll of the said strip shingle I0 is cut away substantially as indicated in Fig. 3 leaving a narrow strip ll of the said dark colored upper portion ll adjacent the lower surface coated portion II which serves to simulate a horizontal mortar joint when the surface coated portion of another corner unit is juxtaposed in butted relationship thereto.

The reinforcing plate I3 is preferably secured to the back of the bent strip shingle i0 shown in Fig. 3 by such suitable means as hot asphalt or other cementitious material ll. The said reinforcing plate i3 is vertically offset with respect to the said bent strip shingle It so as to admit of the vertical overlapping of the said bent strip shingle ill with the reinforcing plate projecting above the next lower corner shingle unit, to provide a butt joint between the bent strip'shingles of vertically adjacent pre-fabricated shingle corner units and to provide a butt joint between the reinforcing plates of vertically adjacent prefabricated shingle corner units.

The embodiment of the shingle corner unit A shown in Fig. 3 is right hand. It is obvious that like left hand shingle corner units must be alter nated with right hand shingle corner units when erecting the same to admit of erecting the said shingle corner units with the lower surface coated portion of one shingle corner unit in vertical overlapping relationship with the upwardly projecting end of the reinforcing plate of the next lower shingle corner unit.

Fig. 2 shows a left hand three course high prefabricated shingle corner unit B which is constructed substantially like the said shingle corner unit A previously described except that it is composed of a single three course high reinforcing plate I, one vertically central bent right hand strip shingle it which has a dark colored upper portion II and a brick simulating lower portion i2 and one top and one bottom bent left hand strip shingle llll. which have dark colored upper portions H0. and brick simulating lower portions I20. The lower bent portions l2 and I 2| of the said bent strip shingles II and I" are connected to the said three course high reinforcing plate, I" with the said reinforcing plate I" projecting a short distance above the top bent lefthand strip shingle I" and with the bottom bent left hand strip shingle lllll extendinga like distance below the said reinforcing plate ill. The lower bent corner. portions .of the said 201) left hand shingle Ill,'the said central right hand shingle i0 and the bottom left hand; shingle lllare alldisposed in a vertical plane and in butt joint relationship with each other against the corner of the said reinforcing plate Ill.

n is obvious that the lower portions Hand In of-the strip shingles II and Ill respectively are slightly separated from. the reinforcing plates 13 and Ill respectively when they laterally overlap the upper portiontjlfor iil ofthe, next lower course of bent strip shingles i I. or III as the case may be, which separation-is accomplished during manufacture or erection of the is'aid shingle corner units as required.

The lateral ends ofstrip shingles lLand l ll are suitablynotchedat ii and Ill respectively to cooperate with similar notches il at the ends. of the lower brick simulating portion of the horizontally staggered and vertically overlapping brick simulating strip shingles" shown in dot and dashlines in Fig. 1.. 7 a

By first nailing the one course hlghcorner shingle unit A to the lowest portion of the corner of a structure to be cornered with strip. shingles, andthen securingthe three cohrse high shingle corner unit B in butt Joint relationshipwith. the top said shingle corner unit A which automatically places the lower strip shingle I" .of the said corner shingle unit]; in vertical overlapping relationship with respect to the reinforcing plate ii of the said corner shingle unit A; the corner shingle construction disclosed in Fig.1 is accomplished in which the shingles at the completed corner are positioned in perfect vertical align.- ment, in which the horizontal brick joints are maintained perfectlyhorizontal and which establishes the proper horizontal staggered and vertical overlapped relation of the adjacent strip shingles i1 thereby assuring aperfect simulation of brickwork with comparatively unskilled workmen as erectors.

Although but one embodiment of the invention has been disclosed herein in one and three coursehigh right hand and left hand units, it is obvious hand and left hand forms, and that many changes in the size, shape, arrangement and detail of the various parts thereof may be made without departing from the spirit of the invention as defined in the appended claims.
